Notes & disambiguation

  • The legacy documentation URL (what-is-memorydb-for-redis.html) redirects to what-is-memorydb.html, and on the same date (October 8, 2024) sister caching service Amazon ElastiCache also added Valkey support alongside renamed Amazon ElastiCache for Redis OSS.
  • All underlying technical identifiers—including the memorydb API namespace, aws memorydb CLI commands, memorydb:* IAM actions, and aws_memorydb_cluster Terraform resources—remain unchanged.
